Max10 read checksum error

If my original pof checksum is "aabb_ccdd".

the CPLD after programmed and re power on the voltages, I tried to read code from CPLD, and I get the same usercode but different checksum, it's not same as original pof checksum.

 

the programmer version is 17.2 18.0, 18.1, 19

 

please help to check why the checksum is not same original one.

Hi WShih8,

 

May I know how do you read your original pof checksum? (Is it from Quartus Programmer?)

And how do you readback checksum after power cycle?

 

FYI, Quartus programmer checksum different than general checksum calculations of the .pof.

For more details, please refer to following link:

Thanks😉
